It's not based on a true story. The plot and characters were crafted by the writer for creative purposes rather than being drawn from real-life events.
One way could be to discuss it with others. Sharing your thoughts and listening to theirs might help you uncover aspects of the story that were previously hidden. Another approach is to re-read or re-examine the available information with a fresh perspective.
Perhaps a fanfiction where Arcee has to save Optimus Prime from a mind - controlling device. She has to fight against his altered self and find a way to break the control. This would show her determination and loyalty to Optimus.
A simple Ant Man and Ghost fanfiction could be them having a friendly race through the city using their unique abilities. Ant Man shrinks down and zooms through small spaces while Ghost phases through obstacles. It would be a fun and light - hearted story.
In a fanfiction, Rose could have a dream where she meets Thomas Andrews in a surreal version of the Titanic. He shows her around the ship, pointing out all the safety features he had designed but were overlooked. This dream could be a way for Rose to come to terms with the tragedy. After waking up, she could be inspired to share Andrews' story and advocate for better safety regulations in shipbuilding. The story could be about how his spirit lives on through her actions.
